A plication filed April 12, 1900.

To aZZ whom it may concern.-

Be it known that we, HARRY DAVERKOSEN and LUES NIELsON, citizens of the United States, residing at Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in a Combined Plow and Harrow; and we do declare the following to be afull, clear, and eX- act description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same. c

This invention relates to combined plows and harrows,and particularly to subsoil-p10 ws with harrow attachments, one object being to provide a combined machine of this character pare the same for planting. In other words, it does the work in one operation that would require at least three separate machines todo.

Further objects of this invention are to provide a machine of this character that can be cheaply manufactured, that will be light in draft and the parts of which can be readily adjusted by the driver from his seat, and that will thoroughly do the work required of it.

With these and other objects in view the invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of the combined plow and harrow. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation; Fig. 4 is a transverse vertical section through one of the supporting-wheels removed from the machine. Fig. 5 is a detail transverse vertical section through the tongue and inverted- T- shaped draft-head.

Like characters of reference denote like parts throughout the drawings.

The main frame of the machine is preferably constructed of light metal bars bolted together to form an open right-angular shaped frame composedof the side bars 1 and 2 and the front and rear end bars 3 and 4:. The side bar 1 ofth e frame is bent laterally about midway its length, forming the portion 1, then rearwardly and bolted to the end bar 4:, the front end bar 3 being formed by a reverse laterally-bent portion of the side bar 1, the

stun No.12,589. (N0 model.)

The forward end of the side bar 2 of the main frame is curved downwardly and forwardly and pivotally bolted to the clip fas tened to the axle 5 of the front supportingwheels 6; c

The rearendof the main frame is supported by the rear supporting-wheels 7 and 8, the wheel 7 being joiirnaled on the laterally-projecting arm of a'vertical standard 9, having a pivotal connection with the vertically-adjustableframe 10, having a sliding engage 'ment with the bracket 12, rigidly attached to the side bar 1 of the main frame. 1 The bracket 12 has a rearwardly-projecting arm 13, on the outer end of which is formed a segmental rack 13, and a laterally-projecting stud-bolt 13", on which is pivoted an adj usting-lever 1i, carrying a spring-actuated detent which engages the segmental rack13. The lever 14: is provided with a forwardly-projecting arm 14:, having a slot therein in which engages a laterally-projecting stud 10 of the Verticallyadjustable frame 10, and by means of the lever 1% the frame 10 and-the wheel- 7 may be raised or lowered, as desired. The upper end of the frame 10 is provided with an inwardlyprojecting horizontal segmental rack 10. The upper end of the wheel{standard 9 is provided with a rigid inwardly-projecting arm or lever 9*, carrying on its under side a spring-actuated detent 9 for engaging the segmental rack 10 so that by movingthe lever 9 the wheel 7 may be turned and held in any desired position, which will throwthe machine from one side to the other on its pivot on the front axle, thereby causing the furrow made by the plows to be increased or diminished in width according to the direction the wheel 7 is turned.

The wheel 8 is journaled on a laterally-projecting arm of a vertical standard 15, having its upper portion 15 bent inwardly and journaled in rearwardly-projecting bearing-lugs 16, rigidly connected with the rear cross-bar 4 of the main frame. The standard 15 is pro vided with a rigid upwardly-projectinglever 17, carrying a spring-actuated detent,-which engages a segmental rack l7, rigidly connected to side bar 2 of the main frame and projecting rearwardly in the path of said detent. Thus by actuating said lever 17 the standard 15 is rocked and the supportingwheel 8 thrown backward or forward, which out of engagement with the ground.

The rear end bar 4 and the portionl of the side bar 1 are'connected and braced bya short longitudinally-extending bar 18. This bar 18 is provided about midway its length with an angular bracket, to which is bolted oneend of a transversely-extending bar 19, being bolted neanits opposite end to a similar angular bracket, which is in turn bolted to the side rail2. These two auxiliary bars serve as braces to the main frame and also as supports to the various working parts of the machine, as will hereinafter appear.

201 denotes the subsoil-plow, the standard 21 of which is preferably formed of a part of the forwardly-extending beam 22. Rising from the moldboard of this plow is an upwardlyand rearwardly curving bar 23, the vfree, end of which is pivoted to .the angular brackets 23, fixed to the under side of the transversebarlQ. The landsi-deof this plow is. provided with a similar laterally-and upiwardly extending"supporting-bar 24, having its'free end pivoted on the reduced extreme end of the bar 19 outside the main frame, as shown, The, beam 22 is provided at its forward end with anupwardly -exten ding slightly-curved arm 22,havin g vertical movement through a guide-bracket22 fixed upon the inner si-de of the side bar 2.

25 denotes a rigid arm bolted to the side bar 2,immediately in the rear of the guide.- .braeket 22 On the upper end of the arm25 is formed a segmental rack 25'. Pivoted to 1116 31111 2 5:isarearwardlyinclined adj l stinglever. 26, carrying a spring-actuated detent foren-gaging the rack 25. The forward end of the lever 26' is pivoted to the upper end of thearm 22 of the plowsbeam 22 in one of a series of adj listing-holes provided in the upper end of said arm 22". By actuating the lever 26 we are enabled to raiseand lower the plow-beam and to remove the plows en; tirely out of the ground.

2:7, denotesthesurface plow, having an adjustable standard 17 bolted to the beam of the subsoil-plowand immediately in, front of the same.

It will be seen from: this construction that we are able to vary the width and depth of thefurrow. The surface plow can beset to turna furrow seven inches wide and from two totfour inches deep. The subsoil-plow can be lowered to plow from six to twelve inches deep and a fur-row fourteen inches wide. It wi-llalsobe seen thatasthe surface. plow turns a seven-inch lap the subsoil-plow, coming behind and; making a fourteen-inch furrow, turns, the seven-inch lap over into the bottom of the furrow. Thus'the topsoilisthoroughly coveredby the subsoil, this being of great ad;

all vegetation should be worked deeply into the ground and well covered.

Depending from near the ends of the side bar 2 and brace-bar 18 are slotted hangers 28, suitably braced by the inclined brace-bars 28'. 29 denotes journal-boxes having a vertically-slidable connection in the slotted han gers 28 and being normally pressed downwardly by the coiled springs 30, confined within the slots of the hangers 28, between the upper wall of said slots and the top of the journal-boxes 29.

31 denotes a transversely-disposed shaft .the endsof which are journaled in the boxes 29. The shaft 31 carries the disk and rotary spading-harrows 32, located on thejsaid shaft in the rear and to one sideof the plows. This harrow serves to spade up or loosen the soil and being under the control of the coiled springs will give toany unevennessof the ground n t In the portion of the main frame formed by the rear end bar 4, the brace-bar 18, the rear portion, and the portionl" of the side .bar 1 is a frame for carrying the tooth-barrow now to be described. The said frame consists of two parailel longitndinally-disposed hangers 3,3, bolted at their upper ends to the side bar 1 and the brace-bar 18 of the main frame and having in their lower side pieces a series of bearings in which are jjournaled the reduced ends of a series of horizontal transversely-disposed tooth-bars 34:, carrying downwardly-depending slightly-curved harrow-teeth 35, and having upon their upper sides short upwardlyextending arms36, consh own these tooth-bars to be three in number, carrying, respectively, three and four teeth, but it is obvious that any number of bars carrying any number of teeth might, be used. 1

Rigidly'connected' to the forward tooth-bar 34 is an upwardly-extending lever 38, carrying a spring-actuated detent which engages the teeth ofa segmental rack 39, fixedto the brace-bar 18. It will beseen that by:-actnating the lever 38 the tooth -.b ars 34 will be rocked and more or less inclination will be given the barrow-teeth 35,; which will thoroughly pu-lveriz'e the'soiland prepare the same for planting In order that the drafton this machine shall be equal and light, we provide a novel form of draft connection now to be. described.

Fixed on the inner end of the tongueis a plate 43; having upwardly and inwardly Confined? withinthese flanges and havingsliding-engagement with the; plate 43 is an inverted-T-shaped head 44:, having a rearwardlyseXte 'ldinglug 44;", pro- IOU We have at its outer end the singletrees 49.

vided with an eye which is engaged by a twopart draft-hook 45.

46 denotes a draft-chain the inner end of which is connected with the beam 22 of the plows and the outer end of which is connected with one of the members of the two-part draft-hook 45. 47 denotes a similar draftchain having its inner end connected with the portion 1 of the main frame and its outer end connected to the other member of the two-part draft-hook 45.

Bolted to the head 44 is the usual clip, in which is pivoted the whiifletree 48, carrying By the construction just described an easier and more equal draft is provided, necessitating but one team of horses to draw the machine. The singletrees 49 are provided at their outer ends with the trace connections, consisting of a rearwardly-extending hook 50, the free end of which extends through an eye in the end of a flat spring 51, bolted to the rear of the singletree, thereby preventing any possibility of the cockeye on the end of the trace becoming unhooked.

Rising from thetransverse brace-bar 19 is a seat-standard 52, preferably constructed of light spring-steel and upon the upper end of which is mounted the square seat 53, formed, as shown, of a single piece of sheet metal.

Referring particularly to Fig. 4 of the drawings, we have illustrated a novel form of supporting-wheel which is to be-used on our machine and which we construct in two sections (1 and I), cast independently of each other and provided with a series'of radiallydisposed perforated lugs 0, cast upon the inner peripheries of the wheel-rims and which will when the two half-sections of the wheels are assembled be coincident with one another, and the perforations therein will register to receive the bolts (1 for clamping the two sections together. A wheel constructed as thus described will be stronger and more durable than those now in use.

In view of the foregoing description, taken in connection with the accompanying drawings, the construction and operation of our invention will be readily understood and a further description is not deemed necessary.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described our invention and setforth its merits, what we claim as new, and desire to secure by Letters Patent, is-

1. In a machine of the character described, the combination with the supporting-frame, of a subsoil-plow having rearwardly-projecting arms which are pivoted to the frame, a forwardly-extending beam connected to the subsoil-plow, and having its forward end projecting upwardly, a surface plow bolted to the said beam, and an adjusting-lever pivoted to the upwardly-projecting end of said beam, and provided with means for looking it in adjustment, substantially as set forth.

2. In a machine of the character described, the combination with the main frame and a bracket secured thereto, and provided with a segmental rack, of a sliding frame mounted to slide vertically in said bracket, and a standard having a pivotal connection with said frame, and having at its lower end an angular extension upon which is journaled a wheel, an adjusting-lever pivoted to said bracket and provided with a spring-actuated detent to engage said segmental rack, a segmental rack carried by said sliding frame, an arm projecting inward from the upper end of said standard, and a spring-actuated detent car= ried by said arm for engaging the last-named segmental rack, substantially as set forth.
